more qualified people that can help the society they would be joining (advantage)

harder for criminals to sneak through (advantage)

less people willing to do needed jobs - care workers (disadvantage)

result in lowering of birth rates as they would be educated so they will want jobs not families first(disadvantage)

comparison:

Open door policy is more useful for countries with ageing populations as the immigrants would increase the birth rates whereas points based would probably lower it as the women who migrate into the country would probably be well educated- not looking to have kids early.
